Problems with stackdump in signal handler?

» close window

The Question is:

 
I have a C main program which calls PL/I
subroutines.  When a PL/I subroutine signals
a condition, my C condition handler is called,
but when it calls lib$signal to generate the
traceback, lib$signal crashes and exits the
program.  Why?
 

The Answer is :

 
  The Wizard will assume the use of VAXC$ESTABLISH to establish the
  signal handler in the C code.
 
  Without a concise source code example demonstrating the failure and
  without an example of the stackdump produced by the failure, it is
  very difficult to say why the program might have failed.
 
  Please contact the customer support center for assistance.
